Localization in Wireless PAN
Polok, Zbyszek ; Šimek, Milan (referee) ; Hynčica, Ondřej (advisor)
This bachelor thesis deals with the problem of localization in wireless sensor network. First, ZigBit 900 Modules equipped with chip for wireless communication (AT86RF212) are used to measure the signal strength in the area of Brno University of Technology. The recorded values are then processed using trilateration localization techniques and Euclidean propagation methods. After detecting negative effects on the calculation of the position sought, a filtering method for the calculated values is proposed. In addition, an algorithm determining a sufficient number of reference values for loss rate is also designed to locate all the positions sought. By virtue of these algorithms the trilateration localization method is optimized.
